Epidermal programmed cell death-ligand 1 expression in TEN associated with nivolumab therapy.

Nivolumab is a programmed cell death receptor-1 (PD-1) antibody used in the treatment of metastatic or unresectable melanoma. Cutaneous reactions are the most common adverse events reported with these agents and are rarely severe or life-threatening. Here we present a case report describing the clinicopathological findings of a patient with a fatal toxic epidermal necrolysis (TEN) eruption associated with use of nivolumab for treatment of metastatic melanoma.

Disordered interactome of human papillomavirus.

Intrinsically disordered proteins (IDPs) and proteins with long intrinsically disordered protein regions (IDPRs) lack ordered structure but are involved in a multitude of biological processes, where they often serve as major regulators and controllers of various functions of their binding partners. Furthermore, IDPs/IDPRs are often related to the pathogenesis of various diseases, including cancer. Intrinsic disorder confers multiple functional advantages to its carriers.
